The Course Navigation Menu is a series of links on the left side of your course that helps you and your students access different course areas.

Canvas also has features that are currently disabled from the student perspective. When enabled, students can use them to navigate directly to assignments, files, and quizzes without sequentially viewing all created content.
As a best practice, we recommend course instructors to add all course files, assignments, quizzes, and discussions into a Module to prevent skipped navigation to sequential content, add all course files, assignments, quizzes, and discussions into a Module.
